(54) POTATO CHAIN MACHINE

I.

The invention relates to an agricultural technique, and more specifically to potato harvesting machines.

Famous potato trailer harvesters, containing a frame, on which a vibrating rod conveyor with a plowshare, a haulm topper, a lump press, a discharge conveyor and bunkers are installed, II).

The disadvantage of these trailed combine harvesters is that they have low productivity, poorly separate the tubers from the ground, damage their large number, raise the layer of soil to even the thickness; a meter or so, although in the whole mass of the land the weight of tubers is no more than two percent.

The purpose of the invention is to improve the quality of the separation of tubers from the ground and increase the productivity of the potato harvester.

This goal is achieved by the fact that the potato harvester is equipped with a ... removal device, the working body of which is made in the form of disks mounted on 20 vertical shafts with knives radially located relative to the shafts, whose profile has an L-shaped shape, the shares are made in a row of pointed rods, with distribution boxes installed above the unloading conveyor. shields.

On the frame above the bar conveyor for interaction with the latter, there is a cam with a drive for its rotation.

In addition, a pneumatic cleaner is installed on the frame above the bar conveyor, the collector of which is H-shaped.

Claims (3)

The potato harvester includes a plowshare 2 mounted in front of the bar conveyor 1, which consists of separate knives 3, fixed on the front 4 and rear 5 connecting plates with a gap between them, opposite 6 rectangular windows, and front 4 and rear 5 connect the supports 6 rigidly to each other made in the form of a triangle. On the rear bar 5, compensators 7 are hingedly mounted. Knife 3 is made of a round bar 8, which has a tip 9 in the form of a cone at the end. Ploughshare on the sides has walls 10, made of rods installed horizontally with a certain gap from each other. A bar conveyor is mounted on a shaft-drum P. In front of the plowshare on a frame, a topper-removing device 12 is mounted, the working body of which is made in the form of disks 13 mounted on vertical shafts with knives 14 radially located relative to the shafts, and the bottom the wall is a view of the blade 15, with the shaft 16 vertically mounted in the center of the disk 16, the opposite end of which has a conical ujecTepHio 17, which interacts with the bevel gear 18 of the horizontal shaft 19, the gearbox 20. Between the rod A composer 21 is installed on the forging conveyors. On the frame 22 there is a discharge conveyor 23 horizontally mounted, on which distributor plates 24 and 25 are hinged. The conveyor frame 26, plowshares are mounted on an eccentric device 27 of percussion action, which consists of an eccentric shaft 28, shaft 29, upper 30 and lower 31 supports, provided with rubber shock absorbers 32. The eccentric device, the supports are resting on the supporting platform, and the circular shaft-29 is attached to the frame 26, which is made with the possibility of vertical movement (Swing). The upper supports 30 are secured, like the round shaft 29, to the conveyor frame 26, and the lower supports 31, as well as the eccentric shaft 28k of the support platform. On the frame of the machine is installed cu. 33, the supporting platforms 34, 35 and the power cylinder 36, the body of which is pivotally mounted through the suspension to the main frame, and the power cylinder rod is pivotally connected to the car body. On the frame above the bar conveyor there is mounted a pneumatic hoe 37, made of a collector 38, which is H-shaped, equipped with nozzles 39, directed perpendicularly to the bar conveyor. The collector is connected to the receiver with a pneumatic tubing. The gearbox 20 is pivotally connected to the stem of the power cylinder 40, and the body of the power cylinder is connected to the carrier beam 41, on which the power cylinder 42 is pivotally mounted, the stem of which is pivotally connected to the frame 26. The supporting beam 41 is rigidly connected by a diagonal 43 with a vertical upright 44. The potato harvester is working machine as follows. Turn on the car engine. In the presence of vehicles, the distribution flaps 24 are installed along the movement of the conveyor 23, the power cylinders 40 and 42 are installed in the working position, respectively, of the topper-removing device .12 and the ploughshare 2. When the machine is moving forward, the wormwood 12 cuts off the root of the tops, and the blade 2 with a certain With an amplitude of vibrations, the tubers break down knives with knives 3 and direct them to a bar conveyor 1, while a part of the ground is sifted into a rectangle of window 1 formed by bar knives 3, and a part of the ground land from Together with the miner, the bar conveyor 1 is sieved due to its vibrations, obtained from the operation of the eccentric device 27 of the percussion action. Additionally, the tubers receive a year air jet of the pneumatic cleaner 37, which cleans the tubers from the ground and dust with a stream of compressed air and pushes the ground into the windows formed rods. Net tubers from rod rod 1 arrive at the unloading conveyor 23, which is installed with a bias towards the body and loads the vehicles with tubers. In the absence of vehicles, move the distributor 24 in the direction of the body at a certain angle, and the tubers from the conveyor belt are sent to the body. When the body is filled with tubers, they are transported to a given place. Claim 1. A potato digging machine containing a frame, on which a vibrating rod transomurter with a plowshare, a topper, a komodavoditel, an unloading conveyor and bunkers are installed; The working body of which is made in the form of disks mounted on vertical shafts with radially located relative to the shafts, the profile of which is L-shaped, and l The machine is made in the form of a series of sharpened bars, and distribution boards are installed above the discharge conveyor. 2. The machine according to claim 1, characterized in that a cam with a rotary drive is mounted on the frame above the bar conveyor to interact with the latter. 3. Machine on PP.
